Product Description:

Technical Data
◆Number of poles:1,2,3,4,1+N,3+N
◆Nominal current In(A): 1,2,3,4,6,8,10,13,16,20,25,32,40,50,63
◇B The short-circuit release is to be set up to 3 In through 5 In.It serves especially for protection of circuits with such devices which do not cause any current surges(lights or socket circuits etc.)
◇C The short-circuit release is to be set up to 5 In through 10 In.It serves especially for protection of circuits with such devices which cause some current surges(groups of bulbs, motors etc.)
◇D The short-circuit release is to be set up to 10 In through 20 In. It serves especially for protection of circuits with devices which cause high current surges(transformers,double-pole motors,motors with heavy start etc.)
◆Nominal voltage:
◇1P (single-pole)~230/400V 50/60Hz
◇3P (three-pole)~400V 50/60Hz
◆Rupturing capacity:
◇EN60898-10,000A(nominal short-circuit and operational rupturing capacity)
◆Protection:IP40 for a sole MCB with its design, it protects against a hazardous finger or instrument touch as well as against very small foreign objects; It is without any protection against water leakage (water protection is to be solved with design of the switchboard casing)
◆Ambient temperatue: -5oC to +40oC pursuant to EN60898
◆Gauging temperature:+30oC pursuant to EN60898
◆Max.pre-inserted fuse:100AgG(>10kA)
◆Mechanical lifetime:≤20,000 cycles
◆Electrical lifetime:≤8,000 cycles
◆Fastening:By means of an unique snap mechanism(with arrestment in final positions)the carrying DIN strip EN50022,width 35mm, or even onto the falt surface by means of screws.
◆Removal form the DIN strip:
◇By means of an unique auxiliary snap mechanism, the MCB誷 can be removed even from a row of devices mutually interconnected by a forked or reed rack strip without necessity to dismantle the whole interconnecting strip.
◆Input terminals:
◇Clip terminals(with barrier layer), snap-locked against the worse input of a conductor
◇The input and output can be interchanged
◇They enable more conductors as well as interconnecting strips to be connected
◆Connect ability of conductors (Maximum cross-sections):
◇35mm2 solid conductor
◇25mm2 stranded conductor
◆Terminal protection:IP20
◆Tightening moment for terminals
◇2Nm(combined slotted-head screw)
◆Manufacture standard
◇EN60898,same to IEC 60898
◆Selectivity calss:3
◆Colored levers:
For better distinction among circuits in the switchboards,we supply also miniature circuit breaker with distinction of nominal currents by means of colored levers corresponding to the colors of turn fuses
◇8A(Light green)
◆Can be delivered also with only black levers

Q:Household leakage circuit breakers, circuit problems
Leakage circuit breaker DZ47LEC63, electric problem. Anxious ~ ~ ~ ~ ~ reward points: 80 - from the end of the problem there are 14 days 23 hours 1
Q:Circuit breaker generally choose what ah?
Leakage protection is protected by a relative leakage or electric shock current that occurs within the detected grid and is fully protected as a trip signal and electrical trip task.
Q:How to look at the circuit breaker capacity is how much?
Circuit breaker contact separation instantaneous short circuit current cycle component RMS value of the thousand.
Q:How to distinguish between disconnectors, circuit breakers?
It is a no arc device switch device
Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
measuring and monitoring instruments, relays, automatic devices, etc. through the control cable into the circuit.
Q:The specific function and operation mode of the auxiliary switch on the circuit breaker switch
High-voltage circuit breakers generally have a number of auxiliary contacts, their on-off and circuit breaker main contact the same (or vice versa), so the secondary circuit
Q:How to choose a circuit breaker for home and small office circuits
Leakage accessory handle. Leakage causes not removed before the small circuit breaker handle and leakage accessory handle can not be reset.
Q:Does the isolator and circuit breaker able to switch to each other?
Yes, it just provides a clear breakpoint, and now there are visible breakpoints that have obvious breakpoints.
Q:The difference between the leakage switch of the air switch circuit breaker
Circuit breaker It is a switch function, but also to automatically protect the low-voltage distribution of electrical appliances. Its role is equivalent to the knife switch. Fuse. Thermal relay and other electrical components of the combination
Q:Isolation switch, circuit breaker, open the three What is the difference between ah
The full name of the air switch is an air type low voltage circuit breaker belonging to the circuit breaker which is mainly used in low voltage circuit
